It was a good week for my Creative Thinking class. Once an idealistic brainchild led by two terrified first-time TYO teachers, the pilot class is really starting to come into its own.

Heading into the class eight weeks ago, one of my major goals was to convince our kids that sometimes, it’s totally fine to be wrong. Getting the right answer isn’t always the point; it’s the process of reasoning that refines our logic and molds us into lean, mean critical thinking machines. Being wrong about things is what makes us human – it’s the proverbial hand on the stove top or super hot pepper that your brother dared you to eat. It might not be your proudest moment, but being wrong is what makes us grow.

To that end, I assigned a class project for which being right was victorious and being wrong was hilarious. The kids were each given a water balloon and told that in half an hour, we were dropping it off the roof. Their assignment was to create a protective barrier to prevent the balloon from breaking from the collision.

After a solid three minutes of staring at their balloons and fighting every ounce of kid instinct telling them to forget the project throw it directly at their teacher, they got to work. What resulted was nothing short of a miracle. There were no squabbles over materials, no moments of frustration, no asking for the answers – just good old fashioned hard work. They squinted their eyes and pursed their lips as they taped pieces of cushion and foam and newspaper around their fragile balloons. A half hour later, it was show time.

Only four kids out of two classes successfully protected their balloons from utter destruction, but it didn’t seem to matter. They laughed as volunteer Imad counted down from three before he released each kid’s creation. They laughed even harder when the balloons exploded all over me and my translator, Jamila. They smiled and shrugged when I held up the popped balloons with a grin, and four of them jumped up and down and hi-fived their friends while raising an dry, intact bundle triumphantly over their heads.

When we got back to the room, we asked if they’d had fun. The answer was a resounding “Ah! Ah! Ah!” (kid translation: yes, we did.) The activity wasn’t about being right – it was about learning that sometimes failure is okay. Especially if it soaks your teacher with a water balloon.
